LLC's shall be classified consistent with Federal income tax purposes.A combined controlled group is three or more corporations each of which is a member of either a parent-subsidiary group or a brother-sister group, and at least one of which is both the common parent of a parent-subsidiary group and also a member of a brother-sister group. Two or more life insurance companies subject to tax under section 801 which are members of any parent-subsidiary, brother-sister, or combined controlled group will be treated as a controlled group of corporations separate from any other type of controlled group to which these corporations would otherwise belong if they were not life insurance companies.The life insurance companies that make up a life insurance controlled group do not have to be in a direct ownership relationship with each other.However, a Form MO-1120S return must be filed to fulfill the S Corporation's franchise tax liability, and payment of franchise tax must be paid if the corporation's assets (in or apportioned to Missouri) exceed one million dollars for franchise taxable years beginning on or after January 1, 2000, or ten million dollars for franchise taxable periods beginning on or after January 1, 2010, through December 31, 2015.For franchise taxable years beginning on or after January 1, 2016, no franchise tax will be due.
See A corporation must file Schedule O with its income tax return, amended return, or claim for refund for each tax year that the corporation is a component member of a controlled group, even if (1) no apportionment plan is in effect, or (2) the amounts apportioned have not changed from the previous tax year. If any of the component members of a controlled group are also members of a consolidated group, then the common parent of that consolidated group must file, as part of its consolidated income tax return, one Schedule O on behalf of the members of that consolidated group.
